Relative humidity, expressed as a percent, is a measure of the amount of water vapor that air is holding compared the the amount it can hold at a specific temperature.

Humidity is a measure of water vapor in the air. Meteorologists typically describe water vapor in the atmosphere in two different ways: absolute humidity and relative humidity.

Oct 19, 2023 · Humidity is the amount of water vapor in a given volume of air. Knowing exactly how much water is in the air in specific regions is essential for accurate weather forecasts.

Jan 9, 2026 · Relative humidity is the water-vapour content of the air relative to its content at saturation. Saturated air, for example, has a relative humidity of 100 percent, and near the Earth the relative …

Jan 8, 2026 · Heat waves are becoming commonplace, and so too is high humidity, which can strain the electrical grid, hurt the economy, and endanger human health. But the global prevalence of record …

Most weather forecasts you see refer to relative humidity, so it’s useful to know how this value is computed. On a warm 76°F day, you measure that there is half a gram of vapor for each cubic yard …
